What is a CTF (Capture The Flag)?

Capture the Flag (CTF) in computer security is an exercise in which “flags” are secretly hidden in purposefully-vulnerable programs or websites. Competitors steal flags either from other competitors (attack/defense-style CTFs) or from the organizers (jeopardy-style challenges).

Security CTFs are usually designed to serve as an educational exercise to give participants experience in securing a machine, as well as conducting and reacting to the sort of attacks found in the real world (i.e., bug bounty programs in professional settings).

Classic CTF activities include reverse-engineering, packet sniffing, protocol analysis, system administration, programming, cryptoanalysis, and writing exploits, among others.

This guide is only to cover in general CTF Challenges and hilight two indiependant ones happeing this year.

NOTE: We will sadly not cover Google CTF due to timing. We also will cover various minor CTF’s such as the ones in the DEF CON Villages in their respective sections.

Recommended OS Platforms:

Kali Linux is a Debian-derived Linux distribution designed for digital forensics and penetration testing that incorporates more than 300 penetration testing and security auditing pre-installed. Kali Linux is distributed in 32-bit and 64-bit images for use on hosts based on the x86 instruction set and as an image for the ARM architecture for use on the Asus Chromebook Flip C100P, BeagleBone Black, HP Chromebook, CubieBoard 2, CuBox, CuBox-i, Raspberry Pi, EfikaMX, Odroid U2, Odroid XU, Odroid XU3, Samsung Chromebook, Utilite Pro, Galaxy Note 10.1, and SS808.

Kali Linux is also available on Windows 10, on top of Windows Subsystem for Linux (WSL). The official Kali distribution for Windows can be downloaded from the Microsoft Store:

For select Android Phones, you can run a derivative called Kali NetHunter. It includes a dedicated NetHunter App with a full Kali Linux toolset providing a touch screen optimized GUI for common attack categories, a custom kernel that supports 802.11 wireless injection with Software Defined Radio support and preconfigured connect back VPN services:

Parrot OS is a GNU/Linux distribution based on Debian’s testing branch (Bullseye) and a Linux 5.4 kernel with a focus on security, privacy, and development. It provides a suite of penetration testing tools to be used for attack mitigation, security research, forensics, and vulnerability assessment. The OS is certified to run on devices which have a minimum of 256MB of RAM and it is suitable for both 32-bit (i386) and 64-bit (amd64) processor architectures. In addition, the project is available for ARMv7 (armhf) architectures available for Raspberry Pi devices. The desktop environments are MATE and KDE.

You have two options for Fedora. First is Fedora Security Lab which provides a safe test environment to work on security auditing, forensics, system rescue and teaching security testing methodologies in universities and other organizations. It comes with the clean and fast Xfce Desktop Environment and a customized menu that provides all the instruments needed to follow a proper test path for security testing or to rescue a broken system.

Network Security Toolkit (NST) is a bootable live CD based on the Fedora distribution. The toolkit was designed to provide easy access to best-of-breed open source network security applications and should run on most x86 platforms. The main intent of developing this toolkit was to provide the network security administrator with a comprehensive set of open source network security tools.

Pentoo, based on Gentoo Linux, is a Live CD and Live USB designed for penetration testing and security assessment. Pentoo is provided both as 32 and 64 bit installable live CD. Pentoo is also available as an overlay for an existing Gentoo installation. It features packet injection patched wifi drivers, GPGPU cracking software, and lots of tools for penetration testing and security assessment. The Pentoo kernel includes grsecurity and PAX hardening and extra patches — with binaries compiled from a hardened toolchain with the latest nightly versions of some tools available. Tools are installed with versioned ebuilds and open-ended ebuilds, making it possible to pull in the latest subversions and still have installs tracked by package management.

BlackArch is an open-source distro and penetration testing distribution based on Arch Linux that provides a large amount of cyber security tools, created specially for penetration testers and security researchers. The repository contains more than 2400 tools that can be installed individually or in groups. BlackArch Linux is compatible with existing Arch Linux installs.

PentestBox is an Open Source, Pre-Configured Portable Penetration Testing Environment for the Windows Operating System. It provides all the security tools as a software package and lets you run them natively on Windows. This effectively eliminates the requirement of virtual machines or dualboot environments on windows. All the dependencies required by tools are inside PentestBox, so you can even run PentestBox on freshly installed windows without any hassle. PentestBox is entirely portable, so now you can carry your own Penetration Testing Environment on a USB stick. It supports both 32-bit and 64-bit systems.

Apple iMac machines run a POSIX compliant UNIX variant, and the hardware is essentially the same as what you would find in a high-end PC. This means that most hacking tools run on the Mac operating system. A properly set up Apple machine can do quite a bit of heavy lifting.

SecBSD Tool List is based off the long running SecBSD Project. SecBSD is an UNIX-like operating system focused on computer security OpenBSD-based. A BSD enviroment for security researchers, pentesters, bug hunters & cybersecurity experts. While the project is in a questionable limbo, for those running OpenBSD you can use their Tool List as a refrence guide to import and config your instance to be a pentesting platform.

DEF CON 30 Capture The Flag

After a spectacular run by the Order of the Overflow, the Nautilus Institute is looking forward to bringing you the future of DEF CON CTF: three days of attack-defense action with sixteen of the best hacking teams in the world. Our teams will be reverse engineering, pwning, and pushing other hackers off their boxes in a head to head computing competition to directly demonstrate effective exploitation for the future.

How to Qualify
DEF CON CTF is a popular contest. Over 1200 teams played in DEF CON CTF Qualifiers in May, with over 200 solving two or more challenges. We qualified the top team from last year’s finals game, Katzebin, and fifteen of the top quals teams. Our competitors hacked their way through an ARM trustzone applet, dug deep into the Missouri Encryption Standard (base64, of course), and pieced together a flag by reverse engineering 24315 binaries for 16 different architectures.

Interested in bringing a team to DEF CON 31? Study up on previous DEF CON CTF challenges, perfect your techniques, and stay tuned for news about how to qualify for the 2023 contest.

Spectating CTF
Visit the CTF room to take in the ambience of the contest. CTF is a marathon, not a sprint, so the vibes in the room may shift as the contest progresses through Sunday.

Enjoy yourself, learn about the game, but please be respectful! The competitors have worked very hard to qualify, and distractions may not be appreciated.

If you have questions about CTF, members of the Nautilus Institute can probably help you with answers!

Brighter Tomorrows
We’re excited to be making the world of DEF CON CTF a better place. As we grow, we hope to allow more disciplines to flex at CTF, and we hope you’ll be a part of that. Thank you to the CTF and DEF CON communities for this incredible opportunity, and we hope to build a brighter future for you all to break.

The journey home to DEFCON 30 for each of us is absolutely unique and special. Whether you grew up alongside the digital world, or you found a mirror to your feelings in cinema, television and music, or your passion for learning and curiously brought you to read every line of a novel, story, chat or blog post, we all share that HACKER spirit. What is a HACKER? Who is a HACKER? Am I a HACKER? Our hope is not draw lines, and barriers in defining HACKER, rather to remind us that HACKER is a culture, a feeling, a love and passion to explore and challenge ourselves. In simplest terms a HACKER can be seen as a solver of quests. As this our 30th year we reflect on our roots, where we have come, and what our future holds. But as with all things to a HACKER, another quest we will embark on, another puzzle to solve and another story to tell. With this preamble we invite you to play along with us our very unofficial DEFCON 30 LINECON CTF!

Last Minute CTF

The Last Minute Capture the Flag [CTF] event is back for another year during Blue Team Con. We’re looking to bring another beginner-friendly CTF competition. As we were happy to announce last time around, this was originally a very last minute thing. This time, not quite so late, but still pretty last minute. However we aim to provide continue to provide a fun game via a unique learning experience. As this is being run at Blue Team Con, all of the puzzles and challenges will be related as best we can to defensive cybersecurity topics.

Our goal is to create somewhat friendly introduction to CTF-style challenges and being very accessible to users of all skill levels. We have reworked and rebuilt how we want to start the competition in effort to help show newer CTF players a bit of what we have going on. To this end, the competition requires you to complete two introductory challenges that walk you through some important information and will hopefully help get you into the spirit of the competition. Remember, we want you to learn, we just might not make everything too easy…

However, a big difference that we can impart on this competition compared to other competitions, as we did last year, is that the Last Minute CTF wants to see you document your work and provide write-ups for each of the challenges. This is totally not because we’re doing this at the last minute and don’t want to do it ourselves… However, half of the available points will come directly from these write-ups. While documentation is not something for everyone, it is a highly desirable skill to have and use in any day-to-day operation and who knows, we may even feature your write-up and tell everyone how awesome you did the thing.

CTF Hours:

The competition homepage will go live for player signups (and to allow people early access to complete the introduction) when registration opens on Friday, August 26th, at 6:00pm CDT.

The rest of the challenges and the competition will begin Saturday, August 27th, at 10:30am CDT until Sunday, August 28th, at 1:00pm CDT.

Help and Assistance:

  • Join the Blue Team Con Discord and then the #ctf channel
  • Stop by the CTF Room during Admin Availability Hours* for Assistance
  • Saturday, August 27th: 10:30am to 5:00pm
  • Sunday, August 28th: 10:00am to 1:00pm
  • These hours are subject to change.

Virtual Event, August 6–7, 2022


HACK@SEC is a competition, coincides with the USENIX Security conference, for penetration testing of the hardware and firmware. In this competition, participants compete to identify the security vulnerabilities, implement the related exploit, propose a mitigation technique or a patch, and report them. The participants are encouraged to use any tools and techniques with a focus on the exploitation of the bugs.

This year, we together develop practical and effective solutions and computer-aided tools to identify the vulnerabilities more efficiently in buggy SoC, with a special focus on exploitation.

The teams will be provided an SoC including a set of bugs and will compete in a live capture-the-flag competition. They will need to apply their techniques and developed tools to detect and exploit as many vulnerabilities in a limited time-frame.

Pros VS Joes CTF

Location: BSides Las Vegas

The Pros V Joes CTF is an event where the average Joe can have a chance to defend along with Professionals in the field, to learn from them while having fun. The game consists of live combat, with each team of Joes defending a network from a Red Cell of professional hackers. Each team of Joes will be lead by a Pro Captain (PvJ Staff) and Pro co-Captain. These fine folks will help train and prepare their Joes, supporting them throughout the two days of carnage and mayhem.

Apply to be a Pro or a Joe or check out our sponsorship opportunities.

As in the past, this game is designed to give regular Joes their first taste of live-fire security, where they have to defend networks against Professionals who know how to break in.

For the Pros, this is a chance to flex your muscles, showing how good you are against live threats. Or, if we accept you to our Red Team to play with our PvJ Staffers, it’s a chance to show your skills in pwning all the things. For both colors of Pro, Red and Blue, it is a chance to lend your experience to help others improve their game.

The environment to host this CTF is laced with various surprises to keep the game interesting. The networks that the Blue Teams must defend will be a mix of Windows and Linux, with the typical Internet services (web, DNS, mail, etc) and a mix of obscure systems and services.

For more information for both Pros AND Joes head over to http://prosversusjoes.net. Also, watch for tweets from @dichotomy1, our Red Blue and Gold teams, or any of the rest of the PvJ Staff.


Website: https://2022.faustctf.net/

CTFTime: https://ctftime.org/event/1598

Date & Time (EST): July 9th 8:00 AM — 5:00 PM

FAUST CTF is an online attack-defense CTF competition run by FAUST, the CTF team of Friedrich-Alexander University Erlangen-Nürnberg.


Once again, the competition will work in classic attack-defense fashion. Each team will be given a Vulnbox image to host itself and VPN access. You will run exploits against other teams, capture flags and submit them to our server.

The vulnbox decryption password will be released at 2022–07–09 12:00 UTC. The actual competition will start at 13:00 UTC and run for eight hours.


Thanks to our sponsors, we can again provide nice prize money:

  • First place: 1024 €
  • Second place: 512 €
  • Third place: 256 €

Additionally, for each service the first team to exploit it, submit a valid flag and provide a write-up will win 64 €.

Please check our rules page for information on payout restrictions.


Testing Vulnbox

Testing Vulnbox images are available. On first login, the Vulnbox will ask you for some information and configure itself properly. You can log in as root using any of the following ways:

  • Use SSH with the generated random password (may need port forwarding, for the NAT Network)
  • Connect to the serial port of the VM (may need configuration)
  • Use the graphical console of your virtualization software — not recommended if you want to deploy SSH-Keys or configure VPN.
  • When hosting on a cloud provider, chances are that you can enter your SSH-Key when creating the VM (cloud-init is installed).

If you run into problems with the setup, try our suggestions from Basic Vulnbox hosting.

We provide two options for download:

To verify the integrity of your download, you may check the SHA512 sums.

Both images are identical, so use the one that fits your needs. The serivces inside are located in `/srv` and are encrypted with the password test.
To decrypt and start them, use the command /srv/extract-services.py /srv/testbox_services.tar.xz.gpg.

Note: Testbox and Vulnbox can not be connected to the game VPN at the same time, so make sure to shutdown the Testbox when the real Vulnbox is released.

Registration open

This year’s website is online and the registration is open. The CTF is already around the corner, so make sure to sign up now.

They can be as simple as posting on your social media or as advanced as building a project and creating a full demo video for it. We’ll leave it to you to choose which challenges you want to take on. Feel free to work collaboratively with others on these.

At GHW: INIT we will have plenty of challenges to keep you busy. Challenges will range from social challenges urging you to connect with other members of the community, technical challenges that will expand your coding skills, and design challenges to refine your skills as a creator and artist. Some of these challenges will be completed live on our twitch stream, so you can follow along and complete it with the community. We cannot wait to see all that you learn, build, and share.
